| Abstract | This research aimed to 1) explore misconceptions about chemical bonds among tenth-grade students, 2) improve and validate three-tier diagnostic tests about chemical bonds in terms of difficulty, discrimination, reliability and validity. The samples for the initial investigation of misconception were 120 tenth-grade students, whereas the samples for the pilot study of the three-tier diagnostic tests were 625 tenth-grade students. The research instruments were an interview form, a two-tier diagnostic test, and a three-tier diagnostic test. It was found that 1) there were 40 misconceptions about chemical bonds among the tenth-grade students. The most common misconception was that the net ionic equation is only written when the product is precipitated (25.33%). 2) Based on Classical Test Theory (CTT) and Item Response Theory (IRT) analysis, there were 80 qualified items on the three-tier diagnostic tests about chemical bonds out of 96 total items. |
